The work, led by Professor Myles Allen at the University of Oxford, was a collaboration between researchers at Victoria University of Wellington, the Universities of Oxford and Reading, and the Centre for International Climate Research in Norway (CICERO). It shows a better way to think about how methane might fit into carbon budgets.

Professor Shine, Professor of Climate Science at the University of Reading's Department of Meteorology, said: "This work builds on a methodology we developed in Reading more than 10 years ago for comparing the climate impact of emissions of different greenhouse gases. The 2015 Paris Climate Agreement, because it specified targets for limiting global temperature change, gave our method renewed relevance. This new paper presents an evolution of our method that is much better suited to the aims of the Paris Agreement than the method that is currently used."
